Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39958, here are decompositions:

  • 5 + 39953 = 39958
  • 29 + 39929 = 39958
  • 71 + 39887 = 39958
  • 89 + 39869 = 39958
  • 101 + 39857 = 39958
  • 131 + 39827 = 39958
  • 137 + 39821 = 39958
  • 167 + 39791 = 39958

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 39958 first appears in π at position 6,075 of the decimal expansion (the 6,075ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
